Superconducting properties study, X-ray diffractometry and TEM investigations of the structure have been carried out on rather exotic superconducting multilayers consisting only of semiconducting materials (chalcogenides of Pb, Sn and rare-earth elements). Superconductivity is discovered in a new combination of semiconductors PbSe/EuS. It is shown that essential features of the multilayers structure determining the appearance of superconductivity are the perfect single crystallinity of entire sample and regular grids of misfit dislocations on the interfaces between two semiconductors. The segregation of free Pb observed in some cases does not correlate with appearance of superconductivity. The possibility of dislocation-induced superconductivity is discussed.
